To more thoroughly and efficiently elucidate potential alterations in the expression of mitochondrial and related proteins, The mitochondrial proteome in motor and parietal cortex has been characterized using Surface-Enhanced Laser Desorption Ionization Time of Flight Mass Spectrometry (SELDI-TOF-MS). Principal component analysis (PCA) and hierarchical clustering techniques were used to analyze the differential patterns of SELDI-TOF spectra to reveal clusters of peaks which distinguished MS from control samples. Nine proteins were found to be responsible for distinguishing disease from control. Peptide fingerprint mapping and liquid chromatography tandem mass spectrometry unambiguously identified these differentially expressed proteins. Five proteins identified are involved in respiration including cytochrome c oxidase (COX) subunits 5a, 5b and 6c, the brain specific isozyme of creatine kinase, and hemoglobin ß-chain. A sixth differentially expressed protein identified was myelin basic protein (MBP), a major component of myelin. Lastly, glial fibrillary acidic protein was found to be differentially expressed. This study provided evidence of key differentially expressed proteins and peptides which play a critical role in the early molecular events in MS pathology and may lead to the development of superior therapeutics agents and possible cures for this disorder.","abstract_html":"Mitochondrial dysfunction has been proposed to play a role in the neuropathology of multiple sclerosis (MS).
